  Similar to our observation that Nanog−/− iPSCs could give rise to chimeric animals, Nanog null ESCs have been shown to contribute to the three germ layers (Chambers et al., 2007). However, in the case of ESC chimeras, Nanog−/− GFP+ liver x receptor were not detected in the germline after E12.5. Bec

  NODAL plays pleiotropic roles in the early embryo. Expression can be detected in the inner cell mass and persists throughout the epiblast until axis specification, when it becomes restricted to the proximal posterior region (Conlon et al., 1994; Mesnard et al., 2006). NODAL activity relies on pro-pr

  Materials and methods Results Discussion Genotoxic stress and DNA damage are considered to be major causes of aging in mammals. The risk of mutation load and loss of genome integrity in adult stem cells has been proposed to be the principal cause of age related decline in tissue function (R

  Materials and methods Results There are a number of complex methods for the generation of neural subtypes from hESCs and iPSCs. In most of them, intact pluripotent colonies are first lifted, induced to form EBs, and then grown in the presence of lineage specific morphogens and growth factors t

  It is now well established that hypoxia between 1% and 5% oxygen facilitates induction and maintenance of immature cellular phenotypes ranging from mesenchymal stem p-Cresyl sulfate to satellite cells and embryonic stem cells (Prasad et al., 2009; Yang et al., 2012), and it appears that this effect

  A recent study showed that mesenchymal ALK5 regulates the balance between smooth muscle versus lipofibroblast differentiation and that ALK5 inhibition shifts the balance towards lipofibroblast (Li et al., 2014). Thus, it is possible that the enhancing effect of ALK5-I we observed in our culture syst

  Electromagnetic field resonance and signal transduction The application of EMF signals appears to be more than a new tool in biophysics and information medicine. It uses the basic science of physics, which drives the chemistry and the biology, to effect a biological change. Low-frequency EMF is b

  Sca-1−/− mice demonstrate deficiency in MMP activity and enhanced fibrosis in muscle (Kafadar et al., 2009). In addition, these mice develop insulin resistance and glucose intolerance when exposed to a HFD (Staszkiewicz et al., 2012). Recent studies suggest that Sca-1+ Ketorolac tromethamine salt

  Cell adhesion molecules (CAMs) are transmembrane proteins that are responsible for mediating adhesion of cells to other cells and/or the extracellular matrix via their extracellular domains, while their intracellular domain interacts with the cytoskeleton. Thus, CAMs provide a direct link between th

  In light of the above findings, we propose that the β-gal+/NeuN+ cells and β-gal+/TH+ cells described by Shan et al. (2006) do not reflect neurogenesis and DA neurogenesis from Nestin+ NPCs, but rather expression of Nestin by mature midbrain neurons. Indeed, given Shan et al.\'s (2006) experimental
